Title: Solid polymer electrolyte fuel cell
Inventor: NISHIZAWA NOBUYOSHI
IPC: H01M8/04
Filed: 1994-02-28
Abstract: PURPOSE:To provide a solid polymer electrolyte fuel cell which is compact and has high performance by making at least one of a gas supplying plate and a water supplying plate be permeable to water but impermeable to a gas at least when it is wet. CONSTITUTION:A fuel cell is composed of an electrode-electrolyte film joined body 1, an anode gas supplying separating plate 2, a cathode gas supplying separating plate 3, and a water supplying plate 4. The joined body 1 is produced by joining an electrode consisting mainly of graphite carrying platinum to both sides of an electrolyte film, and recessed grooves to become reaction gas flow routes are formed in one sides of the gas supplying separating plates 2, 3 and layers HL impregnated with hydrophilic resin are formed on the other sides of the plates. The impregnated layer HL of either of the gas supplying separating plate 2, 3 has a function to inhibit a gas from passing while water permeates the layer HL. Especially, when the hydrophilic resin is dampened and swollen, it becomes more difficult for the gas to permeate the layer. On the other hand, water supplied from the plate 4 can reach the joined body 1.

Title: Lock-up control device for automatic transmission
Inventor: ASAI NORITAKA
IPC: F16H61/14
Filed: 1998-02-20
Abstract: PROBLEM TO BE SOLVED: To suppress the oil pressure loss at lockup to the minimum limit by augmentatively correcting the feed oil pressure in response to the rotational frequency difference between the input rotational frequency and output rotational frequency of a fluid transmission device during the coasting of a vehicle. SOLUTION: When a speed change control means S1 judges the completion of a speed change in the lockup control during coasting, a lockup judging means S2 judges whether the relation between a vehicle speed and a throttle opening lies in a lockup-on region or not. If the judgment is YES, a coast judging means S3 judges whether a vehicle is in the coasting state or not based on the throttle opening. If the vehicle is judged to be in the coasting state, a delay means S5 slightly delays a control start then starts the duty control of a lockup-on output. When a differential rotation judging means S9 judges that the differential speed between an engine speed and a transmission input speed lies in the prescribed region, a correcting means S10 applies a throttle pressure correction output process to a throttle solenoid valve 84.
